Plain water switches for controlling level of water. Very simple mechanism and can be easily turned upside down for normally open or normally closed positions. Comes with silicon ring for waterproofing.
Item Exactly as described! I am so pleased with my number one store WAVGAT - my go-to for all of my Electronics. Jerry is sending all of my orders well packed and protected - they arrived quick and inside boxes as well. Item as described and that is 5 star for the item above the 5 stars for service and shipping. I had not tested item yet since I am missing parts that will take a while to arrive. thanks WAVGAT
